Get it all. Straw walker separation. The APS threshing system on all LEXION combines works so efficiently that most of the grain is separated out during the pre-separation and threshing process. This efficiency means there is less grain that needs to be separated from the straw by a machine separation system. Each walker is 14.4 ft (4400 m) long and comprised of four aggressive steps fitted with fish-back risers for more aggressive separation action. Large perforations allow grain to be shaken through the walkers onto a pan beneath that delivers the material to the cascade pre-cleaner.
Straw walker separation of the class 7 LEXION 670 is enhanced by the Multi-Finger Separation System (MSS) for extremely effective separation action while maintaining high-quality balable straw. Thorough agitation of the crop mat is critical for high separation efficiency, particularly under difficult field conditions such as wet straw or green straw. The LEXION 670 is equipped with the Multi-Finger Separation System (MSS) to ensure effective residual grain separation under all conditions. 14
